Brief Summary

Cognitive behavior therapy (CBT) has long been known as an effective treatment for anxiety disorders, either when given by a therapist or when self-administered through a computer program. However, the biological effect of CBT remained largely unexplored. Most studies focused on genomic differences and pursued differences in methylation patterns following CBT, but the findings were very limited in scope, especially when comparing responders and non-responders to CBT. In the currently proposed study, the investigators plan to go one step further and look for changes in exosomal microRNAs (miRs) from serum samples taken before and after CBT from Panic Disorder (PD) patients. Notably, miR changes show a much faster biological response than methylation patterns yet had never been used before in PD research. The primary benefit of this work will be in providing biological validation to psychological treatments. PD is a heavy public health burden, associated with significant market potential for both therapeutic and diagnostic uses.

Outcome Measures

Primary Outcomes (1)

  • Differntial expression of plasma exosomal microRNAs

    Exosomes are a type of extracellular vesicles of endocytic origin, used in signalling and cell to cell communication, by transferring proteins, lipids, and variety of RNAs between cells. miRs are short single-stranded RNA molecules that bind to complementary sequences of target mRNAs, causing inhibition of their translation and/or inducing target degradation and affecting brain functioning and mental processes. Will be measured twice: pre and post treatment (post or 6 months, whichever is later, to the maximum of 6 months).

    Pre and post treatment, up to 6 months apart.

Secondary Outcomes (7)

  • Change in Panic Disorder Severity Scale (PDSS)

    Weekly during treatment and at pre and post treatment evaluations, up to 6 months apart.

  • Change in Anxiety Sensitivity Index-3 (ASI-3)

    Weekly during treatment and at pre and post treatment evaluations, up to 6 months apart.

  • Change in Mobility Inventory

    Weekly during treatment and at pre and post treatment evaluations, up to 6 months apart.

  • Differntial expression of whole Blood short non-coding RNAs

    Pre and post treatment, up to 6 months apart.

  • Change in the Five-Dimensional Curiosity Scale (DCS-5)

    Pre and post treatment, up to 6 months apart.

  • +2 more secondary outcomes

Study Arms (2)

Healthy controls

OTHER

40 Healthy controls matched on gender and age with no current psychopathology will have exosomal microRNAs measured twice over a 3 month period.

Other: No intervention

panic disorder receiving CBT

EXPERIMENTAL

40 adult patients diagnosed with primary panic disorder will have their exosomal microRNAs measured 2x over 3 months.

Behavioral: CBT- both internet and face to face

Interventions

There are a few common psychotherapies for treating PD, with Cognitive Behavioral Therapy (CBT) as the most common. The most known type of CBT for treating PD consists of two major strategies: cognitive restructuring, and interoceptive and structured exposure to bodily sensations that have become associated with panic attacks (D H Barlow, 1997). The ICBT therapy is based on Barlow and Craske's (2007) protocol for treating PD with elaborations (Huppert \& Baker-Morissette, 2003). It includes six modules containing psychoeducation, cognitive restructuring, exposures, acceptance, and consolidation of gains and relapse prevention. The online modules include reading passages, worksheets, videos, and homework assignments. After completing each module, participants practice related skills and complete homework assignments. The treatment is up to 16 weeks long; participants are encouraged to complete the treatment within this time period, and reminders are sent to monitor their progress.

panic disorder receiving CBT

Healthy controls will not receive any intervention.
